盐酸治疗代谢性碱中毒已日益为临床所采用,但以前只能通过中心静脉导管给药。本文介绍了一种通过外周静脉输注盐酸的新方法,并附2例病例报告证明这种方法是安全的。方法:将盐酸制成含量为5 mol/L的无菌液,密封在10ml的玻璃安瓿中,每安瓿含盐酸50mmol。使用商品氨基酸输液为盐酸的缓冲剂(采用三种氨基酸输液:1.Intramin Forte 17.2gN/L; 2.Amodex 12.0gN/L;3.Vamin9.4gN/L),每种氨基酸输液中加入盐酸量为150mmol/L。经液相层析法分离和比色法测定及色氨酸测定,证明各种氨基酸在盐酸中是稳定的。输注装置:采用没有金属部分或套管的耐盐酸的聚苯乙烯与尼龙制成的滤器(Sangofix O-U),输注时,通过离套管末端20cm处的一个叉管,使氨基酸/盐酸液与20%脂肪乳(Intralipid)以2:1量混合,混 Hydrochloric acid treatment of metabolic alkalosis has increasingly been used clinically, but previously only through the central venous catheter. This article describes a new method of intravenous infusion of hydrochloric acid through a peripheral vein, with 2 case reports that demonstrate this approach is safe. Methods: The hydrochloric acid was made into a sterile solution with a content of 5 mol / L and sealed in 10 ml glass ampoules containing 50 mmol hydrochloric acid per ampoule. A commercial amino acid infusion was used as a buffer for hydrochloric acid (using three amino acid infusions: 1. Intramin Forte 17.2 g N / L; 2. Amodex 12.0 g N / L; 3. Vamin 9.4 g N / L) 150 mmol / L. The liquid chromatographic separation and colorimetric determination and tryptophan determination, to prove that a variety of amino acids in hydrochloric acid is stable. Infusion set: A filter made of Hydrochloric Acid-Resistant Polystyrene and Nylon without metal part or cannula (Sangofix OU) was infused through a fork pipe at 20 cm from the end of the cannula so that the amino acid / hydrochloric acid solution Mix with 20% fat emulsion (Intralipid) in a 2: 1 amount and mix
